Thanks! For some reason it wont run for me (the demo)... I get an error message saying some file cannot be found. Movie worked perfectly.

Yeah, same message I got, that's why I think it's DX10 only. The message I got was that d3d10.dll couldn't be found. Isn't that a DX10 file or does that just mean it won't run on my WinXP 32bit installation?
